1,4-二氨基-2,3-二氯蒽醌合成的新工艺

A New Synthesis Process for 1,4-Diamino-2,3-dichloroanthraquinone

将1,4-二氨基蒽醌隐色体在溶剂中直接通入氯气进行氯化,可以得到色谱含量98%以上的1,4-二氨基-2,3-二氯蒽醌,收率93%左右。

1,4-Diaminoanthraquinone leuco could be directly chlorinated by chlorine gas in a solvent,and 1,4-diamino-2,3-dichloroanthraquinone which content(HPLC) more than 98% was obtained.The yield was about 93%.
